assistant

The Battle of Thermopylae was a fight that took place in 480 BC between an alliance of Greek city-states and the invading forces of the Persian Empire. The Greek forces were led by King Leonidas I and made up of just 300 Spartan soldiers and numerous allied troops. Despite being heavily outnumbered, the Greek forces were able to hold the line against the Persians for three days before they were ultimately overwhelmed and defeated.
